Hammering on and pulling off:
Hammering On and Pulling Off happens when you can strum on one note and successfully hit the notes that come after it without using the strum bar. Look for the single notes with white rings on top instead of black rings. As long as you hit the previous note, you can hit the next note by pressing the correct fret button. This is especially useful on songs like Cult of Personality under the Hard difficulty setting.
